Embodiment
The embodiment of technical solution of the present invention is described in detail below in conjunction with attached drawing.Following embodiments are only used for
Clearly illustrate technical scheme, therefore be only used as example, and the protection model of the present invention cannot be limited with this
Enclose.
The present invention provides a kind of pipe repairing method, is carried out in the present embodiment by taking the restorative procedure to petroleum pipeline as an example detailed
Describe in detail bright.As shown in Figures 1 to 5, more detailed introduction is carried out to the pipe repairing method with reference to step S01-S06.
S01 the reparation section 100 of the pipeline), is determined, and by the both ends difference dredge operation hole of the reparation section 100 simultaneously
Disconnected pipe；
Specifically, according to pipeline construction G- Design to be repaired and reconnaissance trip, duct segments point and elbow transformation point are specified,
Determine the reparation section 100 of pipeline, and operation hole and disconnected pipe are excavated at the both ends for repairing end.The place refers to disconnected pipe and refers to repairing
The two of section 100 bring out, i.e., disconnect pipeline in the position in operation hole.When determining to repair section 100 as far as possible, it should avoid in complexity
Terrain, such as geology is harder, building, waters or hollow mire etc. are not easy the place of constructing operation as repairing section 100
Endpoint, i.e., as operation hole tap point.In addition, also needing to consider the quantity for repairing 1.5D elbows in section 100, section 100 is repaired
The quantity of interior 1.5D elbows is selected within two as far as possible, such as one or 2, avoid excessive elbow from influencing to repair pipeline
It is multiple.
In the embodiment, the first operation hole 11 is excavated in the first end for repairing section 100, is dug in the second end for repairing section 100
The operation of pick second hole 12.
S02), the inner surface of pipeline of the reparation section 100 is cleared up；
Specifically, which includes the following steps again：
S021 the foreign matter of the inner surface of pipeline for repairing section 100), is removed；
In the step, to be repaired section 100 of inner surface of pipeline is cleared up, scale removal, iron rust and overlap welding slag
Deng foreign matter so that inner surface of pipeline is smooth.
S022), high density polyethylene pipe is tried on the slotting reparation section 100, if inserting process is obstructed or described highly dense
The degree polyethylene pipe face of taking temperature is damaged, then the inner surface of pipeline of the reparation section 100 is handled again, until qualified.
In the step, with high density polyethylene pipe it is exploratory it is interspersed repair section 100 pipeline, if inserting process is obstructed,
Such as run into foreign matter obstruction so that inserting process cannot be smoothed out, then there are larger for the inner surface of pipeline of explanation reparation section 100
Foreign matter or blocking, if examination inserting process in be only high density polyethylene pipe surface serious damage, illustrate to be repaired
There are larger foreign matter for the inner surface of pipeline of section 100.In the case of this two kinds, be both needed to to be repaired section 100 of inner surface of pipeline into
Row is cleared up again, until qualified.
S03 the inner surface of pipeline of the reparation section 100 after), clearing up carries out corrosion inhibiter protection；
In the step, corrosion inhibiter batch processing is carried out to the inner surface of pipeline for repairing section 100, realizes that old pipeline metal surface is delayed
Lose agent protection.

Fold and will wind thereon, such as the section of liner hose is folded into U-shaped, so that liner hose 3, which passes through, repairs section
With smaller by section during 100 pipeline, in favor of passing through.
In the embodiment, liner hose 3 selects high pressure composite hose, for being repaired to the pipeline for repairing section 100.
S042), one end of the liner hose 3 is connected with one end of traction steel wire 6, the traction steel wire 6 it is another
End is connected through the reparation section 100 with pulling equipment 7；
In the step, one end of liner hose 3 is connected through moment of torsion releasing-joint 5 with the first end of traction steel wire 6 first,
And the second end of traction steel wire 6 is passed through and repairs section 100.Then, traction is laid on the ground near the second operation hole 12 to set
Standby 7, and multiple pulleys 4 are laid in the front end of pulling equipment 7, for guiding traction steel wire 6.The second end of traction steel wire 6 is worn
Cross reparation section 100 and be drawn out on pulley 4 and pulling equipment 7.Start 7 traction steel wire 6 of pulling equipment so that traction steel wire 6 is led
Draw liner hose 3 through reparation section 100.
S05), inflated into the liner hose 3, the liner hose 3 is attached in the pipeline of the reparation section 100
On wall；
Specifically, gases at high pressure are squeezed into liner hose 3 so that liner hose 3 expands and adhere well to reparation section
On 100 inner-walls of duct.
S06), the both ends of the reparation section 100 are met and discussed with the termination of the pipeline 200 of adjacent segment respectively and are connected, form pipe
Road is met and discussed connection structure.
